It is fitting that my first post is about the tool I love the most: GNU emacs. It is the text editor, plus a lot more.
Normally, when you just run emacs, it will load your initialization file (.emacs). But, what if you just want to do something quick, and don't want to wait the extra couple of seconds for emacs to load all these other stuff in your init file?
Just run emacs with the -q option. You will have a bare-bone emacs.
